"Because the county system is basically at capacity, the plan would be to go mauka, about the 300-foot elevation, install two wells and storage/treatment facilities to support the project." Harold Edwards, president of ITC Water Management, gave that answer to the Maui Planning Commission in September 2026. He was explaining why the proposed EC Pāʻia Town development would not connect to county water at all.
That answer was about a 170-home project. It applies just as much to a single house on a Pāʻia side street. If you're comparing Pāʻia with other North Shore and Upcountry options, the size of the water meter on the parcel is one of the most consequential lines in the file. Under rules Maui County adopted this summer, that meter now carries a measurable allowance. It sets how much house, how many bathrooms, and whether an ohana unit can fit under one service.
The August letter that set the ceiling
The Maui County Department of Water Supply lists Pāʻia as part of its Central Maui system, which draws groundwater from the ʻĪao Aquifer. On Aug. 14, 2026, the department wrote to the Department of Planning that the Central Maui system was at 98% to 100% of its maximum reliable capacity, with "no additional source capacity" for new or expanded service. Maui Now reported the letter in its coverage of the EC Pāʻia hearing.
The word "expanded" matters most to a buyer. A new meter on a vacant lot is the obvious case, but county rules also count a meter upgrade as a project. The water department's rules on large-quantity requests also tighten once a system forecast reaches the 98% to 100% band. In practice, whether a parcel can get more water is a parcel-by-parcel determination by the department. A water line running past the property doesn't settle it, and neither does a land-use approval.
The department's own pipeline shows how little is moving. Its monthly report for August 2026 recorded one new service, one meter upgrade, and zero reservations countywide. The same report says its 2026 Central System capacity update was near completion, and that buying property with an additional source for the Central system "is currently being considered." Neither is new water yet.
What a meter is worth under the August rules
On Aug. 6, 2026, the department's Chapter 16-203 rules took effect. They replaced the old fixture count with an estimate of daily use. The unit is the equivalent single dwelling, or ESD, defined as 300 gallons per day.
The rules then tie each single-family meter size to a band of ESDs:
| Single-family meter size | ESDs allowed | Gallons per day equivalent |
|---|---|---|
| 5/8 inch | Up to 2.5 | Up to 750 |
| 3/4 inch | 2.6 to 3.5 | Up to 1,050 |
| 1 inch | 3.6 to 6.0 | Up to 1,800 |
Existing homes get a protection that new projects don't. A single-family home keeps whichever is greater, the ESDs tied to its existing approved use or the ESDs set by its meter size. An existing accessory dwelling keeps its approved use or half the single-family meter allowance, whichever is greater. Owners who bought extra fixtures under the old method are credited additional ESDs based on what they paid.
So a home that already has service holds a defined allowance. When the system has no source capacity to grant more, that allowance is the room you have to work with. Two Pāʻia houses with similar lots and similar finishes can therefore have very different upside. A larger meter, or a documented history of approved use, gives one of them more of it.
Running the formula on a Pāʻia remodel
The rules spell out the arithmetic. Indoor demand for a dwelling, in ESDs, is 1.15 times the number of bathrooms raised to the 1.3 power, plus the number of bedrooms, plus 3, all divided by 10. A single-family service adds a flat 0.5 ESD for outdoor use. The exponent means each added bathroom counts for more than the one before it.
Apply that formula to a few renovation plans on a 5/8-inch meter. These figures are illustrations computed from the published formula, not department determinations:
- Three bedrooms, two baths, as built. About 0.88 ESD indoors plus 0.5 outdoors, or roughly 1.4 ESD. That leaves plenty of room under the 2.5 ceiling.
- The same house expanded to four bedrooms and four baths. About 1.9 ESD with the outdoor allowance. It still fits.
- Four and four, plus a one-bedroom, one-bath ohana. The ohana adds about 0.5 ESD, for roughly 2.4 total. It fits, barely.
- Five bedrooms, five baths, plus the same ohana. Roughly 2.75 ESD. That's past the 5/8-inch band and into 3/4-inch territory, which means a meter upgrade, which counts as expanded service on a system with no source capacity left to grant.
Here's what that means for a buyer. The fifth bedroom and bathroom are what push this plan over. A remodel plan drawn before the meter is confirmed could end up depending on water the system has said it doesn't have.
Fees have changed too. Ordinance 6001, effective July 1, 2026, bases water-system development fees on projected average daily demand instead of meter size. It also lets an existing accessory dwelling get its own meter at time-and-materials cost, as long as total demand on the property doesn't go up. The department's approval still depends on source capacity being available.
Outdoor use has its own limit. Ordinance 5929, in effect since March 1, 2026, bars potable-water landscape irrigation from 9 a.m. to 5 p.m. and limits watering to three scheduled days a week. The same ordinance has a pool-cover requirement for private swimming pools, and existing pools must comply starting March 1, 2027.
Why the town's largest proposed project has to bring its own water
The EC Pāʻia Town proposal shows the same limit at a larger scale. Developer Sam Hirbod, through his company EC Paia, proposes roughly 170 homes on about 40 acres of former Alexander & Baldwin cane and mill land. The site sits west of Baldwin Avenue, mauka of Hāna Highway and makai of the former Pāʻia Mill. The plan also includes a medical clinic, neighborhood commercial space, a public parking lot, and a relocated Pāʻia bypass. On Sept. 8, the Maui Planning Commission voted 5–3 to recommend the rezoning to the Maui County Council. Income-restricted units rose to 60 of 170 during the hearing.
Because county service isn't available, the project would rely on private wells drawing from the Pāʻia aquifer and a private wastewater plant. For the 12 months through May 31, 2026, the state Commission on Water Resource Management put pumping from that aquifer at 15.175 million gallons a day, about 217% of its 7 mgd sustainable yield. The commission's Deputy Director, Ciara Kahahane, said the figure was higher than the one it had reported the previous November. Project attorney Cal Chipchase attributed the overdraft to drought cutting irrigation deliveries. The commission said its current work can't determine how much of the pumping traces to that cause. It also said it doesn't have enough detail about the proposed well to comment on its viability.
The timeline is long. Chipchase put permitting alone at five to eight years, with construction to follow. The county's position is that the rezoning can't take legal effect until the state Land Use Commission acts on a district boundary amendment, and the Council has no deadline to act. For someone buying in Pāʻia now, the housing stock with county water is essentially the housing stock that already exists. That's why the allowance attached to each existing meter matters so much.
Why the Pāʻia median can't price the difference
The usual comparison tools don't capture any of this. The Realtors Association of Maui reports Pāʻia within a combined Spreckelsville/Paia/Kuau district. In July 2026 that district closed one single-family sale, at $2,430,000. June 2026 had two sales with a $7,625,000 median. July 2025 had four, at a $2,440,000 median. A median built from one to four sales a month swings with whichever houses happen to close. It can't tell you whether those sales came with a 5/8-inch meter or a 1-inch meter.
Islandwide, the association reported a $1,200,000 single-family median for August 2026, down 7.9% from a year earlier, across 64 closed sales. That's useful background on the market's direction. For a specific Pāʻia property, the meter, the approved use on file, and the remodel plan you have in mind do more to set its value to you.
Questions to settle before you go firm
- What size is the existing meter, and which water system serves the parcel? Haʻikū addresses may be served by the Haʻikū or Kaupakalua wells or the Kamole treatment plant, so a North Shore address doesn't tell you the system.
- What approved use is on record with the Department of Water Supply? Under the August rules, an approved use larger than the meter's allowance can be the figure that counts.
- Did a prior owner buy additional fixtures under the old method? Those payments can translate into extra ESDs.
- Does any existing ohana or accessory dwelling have an approved use on record, or does it fall back to half the single-family allowance?
- Run your renovation plan through the bathroom and bedroom formula before you assume it fits on the existing meter.
- If the plan needs more water, ask the department for a parcel-specific answer, and don't commit to the purchase or the plan until you have it.
Frequently asked questions
Is there a formal meter moratorium in Pāʻia? None of the sources reviewed for this post showed a Pāʻia-specific meter queue or a formal shortage declaration as of early October 2026. What exists is the department's statement that the Central system has no additional source capacity, plus parcel-by-parcel availability decisions.
Does the EC Pāʻia project affect water for existing homes? The project proposes private wells and private wastewater and no connection to the county system. Its rezoning is still before the County Council and still needs state Land Use Commission action.
Does the new ESD method shrink what an existing home is allowed? No. An existing single-family home keeps the greater of its approved use or its meter-size allowance.
